Barnett Engineering ARU CV2 instruction manual Indicators, Troubleshooting

On power-up, following the initial flashing of each LED, Hook flashes until the Cv2 has found cellular service. Once the unit has logged onto the cellular network, the Hook indicator goes out. Hook also flashes while a call is being placed. After the call has been processed, Hook is on steady until the end of the call when it goes out.

Tone blinks once for each DTMF digit that is either received or transmitted.

Voice is on when the Cv2 is speaking. On power-up, following the initial flashing of each LED, it will go on continuously for 2 seconds if any section of the stored database, voice or vocabulary memory is corrupt. If this occurs, the configuration should be downloaded into the unit and the voice recordings checked for validity. Voice flashes briefly every second to indicate that the Cv2 is operating correctly.

1.10Troubleshooting

Is there power to the unit?

When power is first applied to the Cv2, it will flash the Hook indicator until it establishes contact with the cellular service. At any other time, the presence of power, and correct operation, are indicated by the brief flashing of the Voice LED every second.

Does the cell phone work?

Use the local call feature to determine if the unit is working properly. If the call cannot be completed, query the cell phone to see if it responds - any parameter can be used here. Query the RSSI (Received Signal Strength Indicator) in the phone to see if there is coverage in the area. The message “error” will be returned if there is no coverage. This can possibly be corrected by improving the antenna system.
